The best thing to do would be to modify the LayerSwitcher code so that 
it creates a block element for each layer entry and then set the class 
name (depending on layer.inRange) of the element instead of changing the 
style of the span that contains the layer name (around line 301).  This 
would let users decide whether they wanted a gray label or no entry at all.

If you do this, please create a ticket and submit a patch.
